Scanning electron microscopic study on the structure of the lingual papillae of the Karacabey Merino sheep

Amaç: Bu çalışma Karacabey Merinosunda dil papillalarının taramalı elektron mikroskobik incelenmesi amacıyla yapıldı. Gereç ve Yöntem: Araştırmada on adet genç erkek Karaca-bey Merinosu kullanıldı. Dokular dilin apex, corpus ve radix bölgelerinin dorsal, ventral ve ventro-lateral bölgelerinden alındı. Alınan dokular Scaning Electron Mikroskobu (SEM) kullanılarak incelendi.Bulgular: Papilla filiformis, papilla conica ve papilla lentifor-mis olmak üzere üç tip mekanik papilla ile papilla vallata ve papilla fungiformis olmak üzere iki tip tat papillası gözlendi. Papilla filiformis'ler dilin apex ve corpus bölgesinde, ayrıca nadiren dilin apex bölgesinin lateral yüzünde de görüldü. Papilla conica'lar yuvarlak tabanlı ve küt uçluydu. Bu papil-lalar filiform papillalardan daha büyük oluşları ve sekonder papillalarının olmayışıyla ayrıldı. Fungiform papillalar man-tar benzeri ve yuvarlak şekilli, dilin apex, corpus ve radix kesiminde filiform papillaların arasına serpilmiş olarak bu-lunmaktaydı. İki tip papilla lentiformis belirlendi. Birinci tip piramid şeklinde ve sivri uçlu iken, ikinci tip; yuvarlak şekilli ve küt bir uca sahipti. Papilla vallata'da kalın dairesel pedler ve tat tamurcuğu hendekleri belirlendi.Öneri: Karacabey Merinos koyunu dilinde farklı morfolojik özelliklere sahip birçok dil papillasının olduğu belirlendi. Karacebey Merinos koyunu dil papillaları koyun, Saanen ve Jamunipari keçisi ile benzer mekanik fonksiyon özelliklerine sahip olduğu gözlendi.

Karacabey merinosunda dil papillalarının taramalı elektron mikroskobik incelenmesi

Aim: It was aimed to determine the scanning electron mis-roscopic structures of the lingual papillae in Karacabey Meri-no Sheep in this study. Materials and Methods: Ten male young Karacabey Meri-no Sheeps were used. Tissues were received from the dorsal, ventral and ventro-lateral surfaces of the apex, body and root of of the tongue. Tissues were examined by scanning elecron microcopy (SEM).Results: Filiform, lentiform and conical papillae were obser-ved three types as mechanical papillae and fungiform and vallate papillae were observed two types as gustatory papil-lae on the tongue in Karacabey Merino Sheep. The filiform papillae were present on the apex and body of the tongue, in addition randomly determined lateral surface of the apex. The conical papillae were round base and had a blunt tip and these papillae differed from the filiform papillae with their larger size and absence of the secondary papillae. The fun-giform papillae round in shape and mushroom-like, scatte-ring among the filiform papillae on the dorsal surface of the apex, body and the root of the tongue. The lentiform papillae were determined in two types. While the pyramidal-shaped type I lentiform papilla had a pointed apex, the round-shaped type II lentiform papilla had a blunt apex. The vallate papillae were defined bud ditch and a thick annular pad.
